Federal tax law offers no exemption written specifically for Parkinson’s disease, but several income tax provisions for people with serious disabilities apply directly to Parkinson’s patients and, taken together, can meaningfully lower what you owe. The main pieces are the Credit for the Elderly or the Disabled, an itemized deduction for medical expenses, an enhanced standard deduction for seniors, penalty-free access to retirement accounts, and tax-advantaged ABLE savings. Each has its own eligibility rules, and each is claimed on a different form.
The Credit for the Elderly or the Disabled
This is the one federal income tax credit tied directly to disability status. Under Section 22 of the Internal Revenue Code, you qualify by one of two routes: you’ve reached age 65, or you retired on permanent and total disability before the end of the tax year.1Office of the Law Revision Counsel. 26 U.S.C. 22 – Credit for the Elderly and the Permanently and Totally Disabled Many people with Parkinson’s satisfy both. If you’re under 65, the disability path requires a condition that prevents substantial work and is expected to last at least 12 continuous months or result in death.
The credit equals 15 percent of a base amount that depends on filing status: $5,000 for a single filer or a joint return where only one spouse qualifies, $7,500 for a joint return where both qualify, and $3,750 for married-filing-separately.1Office of the Law Revision Counsel. 26 U.S.C. 22 – Credit for the Elderly and the Permanently and Totally Disabled The maximum for a single filer works out to $750. The base shrinks by 50 cents for every dollar of AGI above $7,500 for a single filer, $10,000 for joint filers, or $5,000 for married-filing-separately, which means a single filer’s credit disappears once AGI reaches $17,500. You calculate it on Schedule R.2Internal Revenue Service. About Schedule R (Form 1040), Credit for the Elderly or the Disabled Because the income limits are low, this credit reaches people living primarily on Social Security or a small pension.
Deducting Medical Expenses
Parkinson’s is expensive, and most of what you spend on care is deductible if you itemize. Under Section 213, qualified medical expenses above 7.5 percent of your AGI can be deducted.3Office of the Law Revision Counsel. 26 U.S.C. 213 – Medical, Dental, Etc., Expenses With $60,000 in AGI, only the amount above $4,500 counts, and for a progressive condition the totals often clear that floor.
Deductible costs include neurologist visits, physical and occupational therapy, prescription medications for tremor and motor symptoms, and long-term care services such as nursing home stays or in-home attendants when medically necessary. Specialized equipment like walkers, adaptive utensils, and customized vehicles qualifies. Travel to medical appointments is deductible at 20.5 cents per mile for 2026.4Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents Per Mile, Up 2.5 Cents
Home Modifications
Ramps, widened doorways, grab bars, and accessible bathrooms are deductible when medically necessary, with one important limit. If the modification raises your home’s market value, only the portion of the cost above that increase counts.5Internal Revenue Service. Publication 502 A $20,000 bathroom renovation that adds $8,000 in property value produces a $12,000 medical deduction. Grab bars and ramps rarely add resale value, so their cost is usually deductible in full.
Medical expenses go on Schedule A.6Internal Revenue Service. Instructions for Schedule A (Form 1040) Keep receipts for prescriptions, devices, contractor invoices, and therapy sessions, and keep a mileage log for medical trips.
The Enhanced Standard Deduction for Seniors
Because Parkinson’s is most often diagnosed after 60, the senior standard deduction provisions matter to most patients. For 2026, the base standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly. Taxpayers 65 and older get an additional roughly $2,050 if single, or $1,650 per qualifying spouse on a joint return.
A newer benefit stacks on top. Starting with tax year 2025, an enhanced deduction for seniors adds $6,000 per qualifying individual, or $12,000 for a couple where both spouses are 65 or older, on top of the existing age-based amount.7Internal Revenue Service. Check Your Eligibility for the New Enhanced Deduction for Seniors It phases out once modified AGI exceeds $75,000 for single filers or $150,000 for joint filers, and it’s available for tax years 2025 through 2028.8Internal Revenue Service. One, Big, Beautiful Bill Provisions – Individuals and Workers A single filer aged 65 or older with moderate income can end up with a total standard deduction above $24,000 in 2026. Compare that total against your itemized deductions and take the higher of the two.
How Your Disability Income Is Taxed
Knowing what’s taxable on the way in is as important as knowing what’s deductible.
Social Security Disability Insurance
SSDI can be partially taxable depending on your combined income (AGI plus nontaxable interest plus half your Social Security benefits). Single filers with combined income between $25,000 and $34,000 may owe tax on up to 50 percent of benefits, and above $34,000 up to 85 percent becomes taxable. For joint filers, those thresholds are $32,000 and $44,000.9Internal Revenue Service. Publication 915 (2025), Social Security and Equivalent Railroad Retirement Benefits These thresholds are not indexed to inflation.
Private Disability Insurance
Benefits from an individual policy you paid for with after-tax dollars are generally tax-free. If your employer paid the premiums, or you paid through a workplace plan with pre-tax dollars, the benefits are taxable income. That reversal often surprises people when the first check arrives smaller than expected.
Penalty-Free Retirement Account Withdrawals
Withdrawing from a 401(k) or IRA before age 59½ normally triggers a 10 percent early withdrawal penalty on top of income tax. That penalty is waived for people who are totally and permanently disabled, using the same standard applied to the Section 22 credit: a physical or mental condition that prevents substantial work and is expected to last at least 12 months or result in death.10Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions The exception covers traditional IRAs and employer plans like 401(k)s. Income tax still applies to the withdrawal, but skipping the penalty on a $50,000 distribution saves $5,000.
ABLE Accounts
An Achieving a Better Life Experience (ABLE) account lets a person with a qualifying disability save and invest without losing eligibility for programs like SSI or Medicaid. Investment growth is untaxed inside the account, and withdrawals for qualified disability expenses come out tax-free.11Office of the Law Revision Counsel. 26 U.S.C. 529A – Qualified ABLE Programs Qualified expenses cover housing, transportation, health care, assistive technology, education, employment support, and basic living costs.
Eligibility widened on January 1, 2026. Previously, only people whose disability began before age 26 could open an ABLE account; the threshold is now age 46. That change brings in many Parkinson’s patients whose diagnosis came in their early 40s. The disability must meet SSA severity criteria and have lasted or be expected to last at least 12 months. There is no upper limit on your current age; what matters is when the disability began.12Social Security Administration. Spotlight On Achieving A Better Life Experience (ABLE) Accounts Annual contributions are capped at the gift tax exclusion amount, which is $19,000 for 2026.
Help From Family Members
Relatives who help with Parkinson’s care have two provisions worth knowing.
Credit for Other Dependents
If you provide more than half of the financial support for a parent or other qualifying relative with Parkinson’s, you may be able to claim them as a dependent and take a $500 credit. The person must be a U.S. citizen or resident. The credit phases out above $200,000 in modified AGI for single filers and $400,000 for joint filers.13Internal Revenue Service. Child Tax Credit
Paying Medical Bills Directly
Family members who pay a patient’s medical bills straight to the provider, rather than giving the patient money to pay them, avoid federal gift tax on that payment regardless of the amount. This is a “qualified transfer” under Section 2503 and sits outside the annual gift tax exclusion.14Office of the Law Revision Counsel. 26 U.S.C. 2503 – Taxable Gifts A child could pay $100,000 directly to a parent’s neurology clinic and still give the parent up to $19,000 in other gifts without filing a gift tax return. The payment has to go straight to the provider.
Documentation You’ll Need
Most of these benefits hinge on records. For the Credit for the Elderly or the Disabled and for the retirement-withdrawal penalty exception, you need a physician’s certification that your condition meets the permanent-and-total-disability standard. Keep that statement with your tax records permanently; the IRS can request it.2Internal Revenue Service. About Schedule R (Form 1040), Credit for the Elderly or the Disabled For medical deductions, hold on to prescription receipts, contractor invoices for home modifications, bills from specialists and therapists, and a mileage log for medical travel. Good documentation is often the difference between a benefit you’re entitled to and one you can actually claim.
